Try a hair dryer or heat gun to warm it up and use a stiff nylon or bristle brush to brush up the softened paint.





You could also us acetone to dissolve it but the problem is that concrete is porous and any liquid you put on it will soak in, carrying the pigment with it.





The heat might work best because this will simply soften the paint, not reduce it to a liquid.
Since it's latex it should scrape up easily with a putty knife if it is dry if it is still wet soap and water (use laundry detergent it is non-phosphorous) will wash it safely away.
